Objective:To understand outcome of heroin addicts after abstinence and analyze the factors related to relapse. Methods:A follow-up of 149 heroin addicts in a correction camp was carried out at 6th months after their discharge. Demographic characteristics, clinical features, addiction severity and psychiatric comorbidity were compared between those who relapsed and those who remained abstinent. Results: 22.8% of the subjects were abstinent, 46.3% relapsed, 29.5% in probation or in treatment,1.3% died. Relapse was related to the presence of drug addiction in family members, lack of abstinence intention, antisocial personality disorder, lack of rehabilitation therapy, intravenous heroin use and ASI scores in heroin abuse, composite family/social and legal factors. Conclusion:The outcome of heroin dependence after correction was poor. Relapse was related to family environment, abstinence intention, the heroin addiction severity,antisocial personality disorder.

Objective To monitor the association between the expression of ve-cadherin and mesentery microcirculation blood flow of sepsis CASP rats,Analysis the relationship of each other.Methods Based on the standard criteria,we established sepsis CASP rats,and the rats were divided into several groups according to the gauge of the vein detained needle in the ascending colon,every group has six rats.The groups consisted of Sepsis A group 22 G(0.9 mm× 25 mm,33 ml/min),sepis B group 20 G(1.1 mm ×32 mm,54 ml/min),sepsis C group 18 G(1.3 mm ×32 mm,80 ml/min),sepsis D group 14 G(2.0 mm ×45 mm,270 ml/min),in addition we established the control group.Real-time observation was performed by microscope on the 6 h's blood velcocity of each sepsis CASP rats group.Then we applied the immunohistochemistry to quantitatively analyze the expression of ve-cadherin of each group.Results The blood velcocity of the mesentery microcirculation in control group was (583.21 ±52.39) μm/s,it was higher compared with the sepsis D group(213.30 ±52.39) μm/s (P ＜0.05),the blood velocity in sepsis A group was (482.71 ± 58.62) μm/s,higher compared with the sepsis D group(P ＜ 0.05).The score of the immunohistochemistry quantitative analysis of mesentery ve-cadherin in control group was 11.17 ±0.34,higher compared with the sepsis D group(5.43 ±0.43)(P ＜0.01).The score of sepsis A group was 10.07 ±0.30,higher compared with the sepsis D group(P＜0.05).Conclusions The expression of ve-cadherin of sepsis CASP rats had positive correlation with the blood velocity of the mesentery microcirculation of sepsis CASP rats,and it can indirectly reflect the degree of the sepsis.

Objective To explore the prevalence of autoimmune liver disease-related antibodies in patients with PBC, and study the clinic significance of autoimmune liver disease related antibody profiles in patients with PBC. Methods The anti-AMA in 247 specimens from patients with liver disease, including 173 PBC, 37 AIH and 37 LDC were detected by IIF. Anti-AMA-M2, anti-GP210, anti-SP100, anti-SLA, anti-LCI and anti-LKM-1 antibodies were measured by ELISA. Results The positive rates of anti-AMA, anti-AMA-M2, anti-GP210, anti-SPl00, anti-LC1, anti-SLA and anti-LKM-1 antibodies were92. 5% (160/ 173), 86.7% (150/173), 35. 8% (62/173), 24. 3% (42/173), 0.6% (1/173), 0% (0/173) and 0.6%(l/173) in PBC group, 18.9% (7/37), 5.4% (2/37),8.1% (3/37),13. 5% (5/37),0% (0/ 37 ) ,5.4% (2/37 ) and 2. 7% (1/37 ) in AIH group and 5.4% (2/37), 2.7% (1/37 ) , 5.4% (2/37 ) , 10. 8% (4/37) , 0% (0/37) , 0% (0/37) and 0% (0/37) respectively in LDC group. Anti-AMA, anti-AMA-M2 and anti-GP210 was detected more frequently in patients with PBC group than AIH group (x~2 =101.3,100.8 and 11.0,P<0.01) while anti-SLA was detected more frequently in patients with AIH group than PBC group (x~2 = 9. 4, P < 0.01). The levels of ALT, TBIL, DBIL, GGT and ALP were higher in patients known to have positive anti-GP210 ( U = 1212.0,1199.0,1218.0,1074.0,1030. 0,P < 0. 01) and the levels of IgM were higher in patients known to have positive AMA ( U = 94.0, P <0.05). Conclusions Anti-LCI, anti-SLA and anti-LKM-1 antibodies in PBC and AIH are detected at a very low frequency in the corhort. Anti-GP210 antibody is found to be associated with the severity of liver damage while AMA is found to be associated with immunologic function in patients with PBC. There is little significance for screening anti-LCI, anti-SLA, anti-LKM-1 antibodies in patients with autoimmune liver diseases. It is of importance to detect anti-AMA and anti-GP210 antibodies for diagnosis of PBC.

BACKGROUND:Inflamed dental pulp stem cells are a new kind of dental pulp stem cells, and there is no systematic review on the cells by now. OBJECTIVE:To systematical y review the research progress in inflamed dental pulp stem cells. METHODS:A computer-based online search in PubMed, Web of Science, CNKI, WanFang and VIP databases was performed for related articles published from the establishment of the databases to February 2014. The keywords were“(pulptis or inflam*dental pulp*or human dental pulp with irreversible pulpitis) and stem cel*”in English and Chinese, respectively. Hand searching was also done to obtain further information or papers about the studies. The results were qualitatively analyzed to comprehensively summarize the progress in the research of inflamed dental pulp stem cells. RESULTS AND CONCLUSION:Total y 11 papers were involved in result analysis that comprehensively review the research progress in inflamed dental pulp stem cells at the fol owing aspects:the research of history, material origin, cellculture, cel-surface markers, proliferation ability, multi-directional differentiation potential, animal models and clinical use. Researches of inflamed dental pulp stem cells are stil in the initial stage, and cultivating conditions and the establishment of animal models are stil in the exploratory phase. Controversies stil exist in the capacity of proliferation and multi-directional differentiation of the inflamed dental pulp stem cells. And fewer studies have been done in the characteristics of immunity, subpopulation and clinical use of the inflamed dental pulp stem cells.

Objective:To compare the short-term result of one-stage resection and anastomosis for patients with acute complete obstruction of the right and left colonic carcinoma.Methods:The clinical data of 80 patients undergoing emergency one-stage resection and anastomosis of acute complete obstruction for left and right colonic carcinoma were retrospectively analyzed.Results:Thirty-seven patients were operated on for obstructive carcinoma of the right colon,the mortality was 5.4%(2/37),the rate of complication was 21.6%(8/37),the mean hospital stay and cost was(31.6?12.8)d and(52794.9?60804.3)Yuan RMB,respectively.Forty-three patients were operated on for obstructive carcinoma of the left colon.the mortality was 2.3%(1/43),the rate of complication was 25.6%(11/43),the mean hospital stay and cost was(29.6?14.8)d and(50 192.8 ?39 727.4) Yuan RMB respectively.There was one case of anastomotic leakage in both groups.There were no significant differences of mortality and the rate of complication of the two groups.Conclusions:One-stage resection and anastomosis of acute complete obstruction of left colonic carcinoma can be performed as safely as in those with acute obstruction of right.Intraoperative decompression should be considered seriously in left colonic obstruction prior to the anastomosis following colonic resection.

Objective:To study the clinical application of laparoscopic combined with multi-video debridement in treatment of complicated infectious pancreatic necrosis (CIPN).Methods:The clinical data of 34 patients with CIPN who were treated at the Department of General Surgery, Xuanwu Hospital, Capital Medical University from August 2017 to December 2019 were retrospectively studied. Based on the different video methods used, these patients were divided into 3 groups: the laparoscopic combined with intraoperative ultrasound group, the laparoscopic combined with choledochoscopy group and the laparoscopic group. The number of operations, operation time, blood loss, postoperative complication rates, mortality rates and total length of hospital stay were compared.Results:There were 13 patients in the laparoscopic combined with intraoperative ultrasound group, with age of (56.4±13.4) years. There were 7 patients in the laparoscopic combined with choledochoscopy group, with age of (48.0±8.4) years. There were 14 patients in the laparoscopic group with age of (51.4±15.6) years. The number of operations of the laparoscopic combined with intraoperative ultrasound group, the laparoscopic combined with choledochoscopy group and the laparoscopic group were (2.2±1.1), (1.6±0.8), (2.9±1.4), respectively. The number of operations of the laparoscopic combined with choledochoscopy group were significantly less than that of the laparoscopic group ( P<0.05), but there were no significant differences among the other groups ( P>0.05). The operation time of the laparoscopic combined with intraoperative ultrasound group, the laparoscopic combined with choledochoscopy group and the laparoscopic group were (70.5±22.9) min, (65.7±19.9) min, (51.5±15.4) min, respectively. The operation time of the laparoscopic combined with intraoperative ultrasound group was significantly longer than that of the laparoscopic group ( P<0.05), but there were no significant differences among the other groups ( P>0.05). There were no differences in blood loss, postoperative complication rate, mortality rates and total lengths of hospital stay among the three groups ( P>0.05). Conclusion:Laparoscopic combined with multi-video debridement after making full use of the advantages of each of the video methods, can be used to improve treatment outcomes of patients with CIPN.
